[SOLVED] passing data from one controller to another
Rate Topic:

First of all, I'm loving Yii, many thanks to all the creators and contributors

I'm pretty new to MVC, so I am struggling with parts, but I have a reasonable PHP and OOP background.
Overall, I am getting my head around how it works, but I have a lot to learn...

I am building a blog site starting from the blogdemo base.
I added a Media class to handle images and video I plan to upload.
I'm using the excellent FancyUpload and CThumbCreator, both of which are working well.

I added a button to post/update called 'Manage Media' the links to media/admin taking the post_id with it to only show media for that post. The FancyUpload widget sits at the bottom of media/admin.
CThumbCreator is called at the end of actionUploadedFiles in FancyController.
The saves the files no problem, next I want to add the data to the database.
So just after CThumbCreator does its stuff I created a new Media object, fill its attributes and save it.
This works fine, but there is one attribute I'm struggling to get in FancyController, post_id.
edit - post_id is the foreign key in the Media model linking it to the Post model.

I have tried various ways of saving it in actionUpdate of PostController to later pick it up in FancyController, including sessions and cookies, none of which I could get working.
I'm still learning how to effectively read the class reference so I'm probably making a simple mistake, but I don't have any errors to go on, nothing in the log file.
So my question is, what is the best way to do this? And do you have some example code?
Does my setup seem reasonable to you or is it fundamentally flawed in some way?

Oh man, I got so close to that, just wasn't passing the param in the right place.
Thank you so much, really happy that it now works, I spent far too long on it.
One step closer to finishing my project, happydaves!
